in reply to Is there anything that would not be matched by /\w\W/i ?

There are quite many strings that doesn't match your pattern: Everything that contains only of
  • word characters
  • non-word characters
  • non-word characters followed by word-characters
  • the empty string
If you meant what arhuman thought (/[\w\W]/i) he has forgot that it wouldn't match the empty string, even then.
